Abstract

The occurrence and fate of organotins compounds in drinking water plant in Chongqing of southern China was investigated for the first time. Water samples were extracted by solid phase micro-extraction (SPME) and measured by gas chromatograph (GC) with mass spectrum (MS). Results showed the presence of organotin pollution in drinking water plant in Chongqing and most of organotins was MBT with the highest level of 120.78ngSn/l. Sometimes DBT, MPT and DPT were found. Little endocrine disruptors of TPT (2.77 ngSn/l) was also found occasionally, but TBT was not found. Conventional water treatment process could not removed organotins effectively.
